This invention relates to roll screens and the object of the inventionis to provide a roll screen mounted in a housing and provided with ameans for closing the space be tween the housing and the screen thereinto prevent insects from proceeding along the surface of the screen andthence into the screened room. 7 f

The invention in its broader aspect inay be accomplished in severaldifferent ways and by means of several different devices mounted betweenthe housing and the screen, the'object being to prevent entrance ofinsects into a screened room by passing through the housing for thescreen roller. l 7 Another object of the invention is to provide a rollscreen having a housing in which a sealing member is supported, the saidmemher, being carried by the housing and'riding in contact with thescreen at all times.

A further object of the invention is to provide a U channel carrying afelt strip, the U channel being adjustably mounted on the housing so asto bring the felt strip into conf tact with the screen to maintain theleast possible pressure against the screen and yet effectively seal theopening, the felt strip, by exerting a brushing action on the wirescreen cloth, tending to keep it clean. 7

These objects and the several novel features of the invention arehereinafter more fully described and claimed and the preferred form ofconstruction by which these objects are attained is shown in theaccompanying drawer ings in which Fig. 1 is a section through a rollscreen embodying my invention.

Fig. 3 is a section taken on line 3-3 of Fig. 2. c

Fig. 4 is a section through an alternative form of the device.

Fig. 5 is a section taken on line 55 of Fig. 4.

Fig. 6 is a section through another alternative form of construction.

As shown in Fig. 1, the roll screen comprises a housing 1 having ascreen slot 2 in the bottom through which the screen 3 is movable intoor out of the housing. The

screen 3 is mounted on a'roller 4 rot'atab-ly mounted'in the housingland the screen at the edges is supported'in the channels 5 ex tendingdownwardly from the housing 1. The housing 1 is provided with brackets 67' at the ends by'which the housing is mounted in position and thehousing is provided with ahorizontal bottom 7 extending between thebrackets 6. The edge'of this bottom member 7 forms one edge of the slot2 through which the screen extends.

The bottom member 7, as shown in Fig. 2,

is' provided with a'slot 8 at each end andfa "U shaped metal channel 9is-positionedbeneath the member 7 and carriesia felt strip 10 therein.At each end the channel 9"is pro vided with a bolt 11, as shown inFig.3, whichfexten'ds through the felt strip 10.

The ends of the bolts 11 are inserted through the slot 8, as shown inFigs. 2 and 3, and the nuts 12 are threaded thereon. By this arrangementthe channel 9 and felt strip 10 are adjustable in relation to the faceof the screen 3 so that the felt stripgca'n be moved toward or away fromthe screen to maintain the least possible pressure against the wirecloth and yet effectively seal the opening. The bolts 11 riding in theslots 8 also allow the felt strip to be easily adjusted to compensatefor wear and'by exerting a brushing action on the wire cloth the feltstripgkeeps the wire clean and free from soot or dust. The brushingaction of the felt strip also'brushes any insects off from the screen asit is rolled up and prevents the insects from entering the'housing 1 andproceeding around the screen roller'into the screened bottom edge of thevertical Wallis thus above the plane of the opposite edgeof the'slot;

formed by the lower wall. Any pressure of the-felt strip 10 against thescreen therefore does not cause an engagement of the screen with theopposite edge of the. slot and therefore in applicants constructionthere is little 1;

in the corner of liability of injury to the screen member in operationthereof.

An alternative form of construction for the same purpose is shown inFigs. 4L and 5. In this form a roller 13 is rotatably mounted in theends of the housing and extends over the edge of the slot 2 and intocontact with the wire cloth 8. As the wire cloth is rolled or unrolledit passes over the roller 13 which allows free movement of the wirecloth thereover and at the same time seals the opening between the edgeof the bottom member 7 and the face of the wire cloth. As the roller 13will roll freely in either direction it does not interfere with movementof the wire cloth in either direction and at the same time preventsinsects from passing through the housing into the screened room.

"Another alternative form of construction is shown in Fig. 6 in which ametal strip or partition 141C is hinged to the inside of the housing 1at 15. This strip extends completely across the housing 1 and rests onthe rolled'screen by gravity. As the screen is unrolled the metal stripor partition 14 swings downwardly by gravity and as the screen is rolledup the partition 14: is swung upwardly as the diameter of the screenroll increases. his partition 1% effectually preventsinsects frompassing through the housing from one side of the screen to the other andthus keeps the insects out of the screened room.

From the foregoing description it becomes evident that the device isvery simple and eflicient in operation, will not easily get out oforder,will keep the wire cloth clean, and provides a device which accomplishesthe objects described;

Having thus fully described my invention, its utility and mode ofoperation, what I claim and desire to secure by Letters Patent of theUnited States is- 1. In a roll screen, a housing provided with a screenslot in the bottom and a screen roller rotatably mounted in the housing,a screen mounted on the screen roller and extending through the screenslot, a metal channel, a felt strip secured therein, a pair of boltscarried by the metal channel, the bottom of the housing being providedwith a pair of bolt slots extending toward the screen slot and the saidbolts being adjustable in the bolt slots to alwith the screen.

3. In a roll screen, a housing provided with screen slot into contactwith the screen extending therethrough.

4. In a roll screen, a sheet metal housing provided with a screen slotin the bottom at one side of its longitudinal axis and a screen rollerrotatably mounted on the axis or the housing; a screen mounted on theroller extending through the slot, a flexible strip secured to thebottom wall of the housing and adjustable to contact with the screenwhereby the slot 011 one side of the screen is closed, the constructionbeing such that the opposite edge of the screen slot is above the planeof the first named edge permitting some pres sure to be applied to thescreen fabric by the flexible member without liability of causingengagement of the screen with the opposite edge of the slot.

5. In a roll screen, a sheet metal housing having a horizontal bottomwall and vertical side wall, the two said walls terminating short of thepoint where thetwo planes of the respective walls meet, a roll screensupported in the housing to pass through the said slot, and a flexiblenon-metallic strip adjustably secured to the said bottom wall to contactwith the screen member below the lower edge of said vertical wall.

In testimony. whereof I sign this specification.
